For diagnostic tests the sensitivity, specificity positive and negative predictive value and diagnostic accuracy will be calculated and calculated separately for EUS-FNA during 1st pass, 2nd pass and 3rd pass by comparing the results with the final diagnosis. All results will be expressed as mean, standard deviation (SD) and confidence interval. Testing hypotheses will be used afterwards. An a priori power analysis will be performed to determine the appropriate sample size in order to achieve adequate power for the statistical tests subsequently used. The data from both groups will be compared by standard comparison tests chi-square test or Fishers exact test where appropriate. The level of statistical significance is stated as 0.05.
